Is work force X displacement or distance?

If I carry an object to and fro 10 metres, the work done would be Force x 20 metres. If I carry an object to and fro 10 metres, the work done would be Force x 0 metres.

Why is work done force x distance?

In words: Work is equal to the force that is exerted times the distance over which it is exerted. In equation form: work (joules) = force (newtons) x distance (meters), One joule is defined as the amount of work done when a force of one newton is exerted through a distance of one meter.

Why do we use displacement and not distance to measure work?

When a body is displaced by the application of force,then work is said to be done. but when the body is in circular motion head and tail coincide with each other. then displacement is zero,so work become equal to zero. Hence, displacement and K.E is the measure of work.

What is distance x force?

Work is defined as force times distance. Work is a measure of the energy expended in applying a force to move an object.

Does distance equal force?

Work can be calculated with the equation: Work = Force × Distance. The SI unit for work is the joule (J), or Newton • meter (N • m). One joule equals the amount of work that is done when 1 N of force moves an object over a distance of 1 m.

Does work depend on distance or displacement?

work = force multiplied by distance. in my given example both the displacement and distance is the same.

What is the relationship between distance and displacement?

Distance is a scalar quantity that refers to “how much ground an object has covered” during its motion. Displacement is a vector quantity that refers to “how far out of place an object is”; it is the object’s overall change in position.

Why work is not force times distance?

Why does work equal force times distance? [duplicate] Energy is the capacity to do work and work is the product of net force and the 1-dimensional distance it made a body travel while constantly affecting it.

What does DX mean in physics?

Well, dx means exactly the same thing, with one key difference: it is a differential distance, which is a fancy way of saying very, very, very small. In technical terms, dx is what happens to Dx in the limit when Dx approaches zero.

Do I really need to understand the concept of DX?

The answer to the last question, I’m afraid, is yes. Understanding what dx actually means is not just something you do to feel philosophically pure. There are certain problems where you really need to understand dx: not to take a derivative or an integral, but to figure out what derivative or integral to take!

How do you calculate dy/dx?

Derivatives as dy/dx 1 Add Δx. 2 Subtract the Two Formulas. 3 Rate of Change. 4 Reduce Δx close to 0. You can also think of “dx” as being infinitesimal, or infinitely small. Why don’t you try it on… More

How do you use the dy/dx notation instead of limits?

Here we look at doing the same thing but using the “dy/dx” notation (also called Leibniz’s notation) instead of limits. 1. Add Δx When x increases by Δx, then y increases by Δy : 2. Subtract the Two Formulas 3. Rate of Change To work out how fast (called the rate of change) we divide by Δx: 4. Reduce Δx close to 0
